Same problem here! Chrome shows a blank page where the calendar should be. Works fine in Safari.
I have had problems with Chrome and the calendar before, but a refresh used to fix it. It no longer does.
It shows a blank page... No calendar or settings are shown at all. It is not an empty calendar, but a blank, completely white page
See pic...there's a divider...if you click the divider it reveals the checkboxes to show the activities. At some point in the last month these all went unchecked for me and then the calendar went blank. Check here first....
